OK, I see now the effect of offsets [0 0 ft] below on shading, as well as above on the wall linework where passages cross. Both are worthy effects. And yes, I think reordering submaps will resolve issues with rendering of passages above and below. Bruce

I put in a dot instead of a slash. Argh ... Trying the link again: https://campercaver.net/MiscFiles/CaveSpringCave-Print.pdf Hmmm.... Since this is a map-of-maps, should I change the sequence in which the sub-maps are listed? =============== Bill Gee On 11/12/24 12:49, Bruce Mutton wrote: > Hi Bill > The link to your pdf gives a dns address could not be found. > > Some observations based on what you have written: > A map output without 'selecting' a map will draw component map objects based > on their actual relative passage altitudes (as far as which appears over or > under another). > Once a map is selected, the apparent layering depends on the sequence of > scraps or maps that is written in the map definitions.
